Fund Project: The project was supported by the National Natural Science Foundation of China (No. 20475045) and Scientific Research Foundation of Bureau of Quality and Technical Supervision of China (No. 2005 J0095).

In this work, a sensitive, rapid and simple method for the determination of trace amounts of potassium ferrocyanide in salinized foods and table salt using EV as a RRS probe is established. The detection limit (3σ) of the EV system is 7.8 ng/mL. This new method is more suitable for the determination of the trace amounts of potassium ferrocyanide in colour salinized foods and it can not be disturbed by the color of salinized foods.
